Touchable Holographic Solutions (THS) are an application type in Augmented and Mixed Reality (AR/MR) environments. Evaluating THS requires considering Usability and User eXperience (UX), particularly Immersion and Presence, often overlooked by current methods. A systematic mapping study and exploratory search revealed gaps, such as the lack of a unified instrument for THS usability and UX evaluation, methods that address THS-specific aspects, and challenges in adapting general evaluation technologies. To bridge these gaps, we present the Usability and User Experience Evaluation in Touchable Holograms (UUXE-ToH) questionnaire, with 67 Likert scale items and three open-ended questions. A validation study with 13 experts provided quantitative data and qualitative feedback. Results confirm the UUXE-ToH’s efficacy and offer insights for improvement. This research contributes to Human-Computer Interaction (HCI) by introducing a validated tool for evaluating THS, integrating hedonic and pragmatic aspects, and supporting early problem identification in development, accessible to professionals with diverse UX expertise.

SVR '24: Proceedings of the 26th Symposium on Virtual and Augmented Reality, September, 2024
DOI: 10.1145/3691573.3691584
This study investigates the usability, user experience (UX), and playability of a mixed reality (MR) game called Cubism, which allows participants to interact with holograms using hand gestures. We conducted an experiment with seven participants to evaluate their interaction with the game. The Usability and User Experience Evaluation in Touchable Hologram (UUXE-ToH) questionnaire was the primary data collection instrument to capture participants’ perceptions of usability, satisfaction, and overall experience. Our findings indicate that the mixed reality environment of Cubism offers an engaging and intuitive user experience, though several challenges were identified. These insights contribute to the growing body of knowledge on human-computer interaction in mixed-reality contexts and suggest avenues for improving the design of future mixed-reality games. This research is valuable to the VR/AR/MR community by highlighting the critical factors influencing user interaction and satisfaction in MR games.

Augmented and Mixed Reality enables applications where users engage in natural hand interactions, simulating touch, termed touchable holography solutions (THS). These applications are achievable through head-mounted displays and are helpful in training, equipment control, and entertainment. Usability and User eXperience (UX) evaluations are crucial for ensuring the quality and appropriateness of THS, yet many are assessed using non-specific technologies. The UUXE-ToH questionnaire was proposed and subjected to expert study for content and face validity to address this gap. This study enhances questionnaire credibility and acceptance by identifying clarity issues, aligning questions with study theory, and reducing author-induced bias, offering an effective and cost-efficient approach. The study garnered numerous contributions that were analyzed qualitatively and processed to refine the questionnaire. This paper introduces the UUXE-ToH in its initial version, details expert feedback an alysis, outlines the methodology for incorporating suggestions, and presents the enhanced version, UUXE-ToH v2. This evidence-based process contributes to a better understanding of usability and UX evaluation in the THS context. UUXE-ToH can impact the quality of life of users of solutions applied to education, health, and entertainment by helping develop better products.

Interacting with holograms using the hands is on track to reach a
broad audience in the coming years. Therefore, a current challenge
is understanding how to evaluate this new interaction scenario concerning Usability and User eXperience (UX). In this use context, the
user interacts with virtual objects in your real environment. Some
already known evaluation technologies have been applied to this
type of solution, although they were not created considering aspects
such as immersion and presence, typical in this interactive environment. Thus, this paper presents a Systematic Mapping Study (SMS)
that sought to identify usability and UX evaluation technologies
applied to touchable holographic solutions in augmented reality
or mixed reality environments. Furthermore, the SMS sought to
answer questions about evaluation technologies and holographic
solutions. The SMS examined 3551 publications and selected 40 that
presented 106 usability or UX evaluation technologies in a touchable holographic solution. The results shed light on methods and
aspects little addressed and showed patterns and preferences for
combinations of devices, gestures, and feedback types. This work
contributes to HCI researchers by better understanding the state
of the art of usability and UX evaluation technologies applied to
touchable holographic solutions, classifying them, and discussing
the main gaps and opportunities.

This article presents a study to evaluate the quality of the Porifera
collaborative
tool, which supports
Systematic Literature Review (SLR) and Systematic Mapping Study (SMS) processes. The study
revealed a
high perceived usefulness and ease of use of the tool and identified points for improving the
interface,
such as user feedback and error prevention. The quantitative and qualitative results suggest
that
Porifera is a valuable tool for learning and performing collaborative SLR and SMS. Additionally,
the
article compares Porifera with other related tools, including a discussion on how these other
tools were
evaluated.

SBES'22: XXXVI Brazilian Symposium on Software Engineering, October, 2022
DOI: 10.1145/3555228.3555273
This paper presents Porifera, a collaborative tool to support Systematic Literature Review (SLR)
and
Systematic Mapping Study (SMS). The tool allows the creation of a project for a researchers
team. The
user defines the goal, the inclusion and exclusion criteria for selecting primary studies, the
search
string, and the digital libraries. Also, the tool imports publications and identifies
duplicates. The
selection process occurs with the individual application of criteria and resolution of
disagreements.
During the process, it is possible to observe the agreement and reliability of the researchers'
evaluations. Porifera works on a web platform and integrates external services for translation,
reference citation, and linking publications' files. Porifera's use can improve review and
selection
processes, optimize time, and prevent errors while facilitating collaboration between
researchers.

SBSI’22: XVIII Brazilian Symposium on Information Systems, May, 2022
DOI: 10.1145/3535511.3535531
Context: Systematic Literature Review (SLR) or Systematic Mapping Study (SMS) are a process in
which
publications dataset is systematically analyzed to cover a research field. These processes
involve
multiple investigators collaborating to produce more improved work and often use automated tools
to
facilitate their work. Problem: However, not all tools offer proper support to collaborative SLR
or SMS.
That is, missing a tool to support the study selection process, allowing the collaboration
between
researchers by applying individual criteria and collective decision, supported by agreement or
discussion and consensus. Solution: We developed the Porifera tool to fill this lack. IS Theory:
Technology Acceptance Model (TAM) and a Grounded Theory's phase subset were used to evaluate
Porifera's
tool quality. Methodology: Undergraduate and postgraduate students enrolled in the Experimental
Software
Engineering Research, used the Porifera tool and answered a post-used questionnaire with TAM's
sentences
and other open questions. Then, a quantitative and qualitative analysis was performed. Summary
of
Results: It was possible to see high perceived usefulness and ease of use for Porifera. Too it
noted the
effectiveness of resources to support the collaborative activity and its contribution to
learning and
performing a collaborative SLR or SMS. The evaluation showed points to improve the Porifera's
interface.
Contribution and Impact in the IS area: The Porifera is an IS for data, information, and
knowledge
research management because it gathers publications records and allows it will be interpreted
and
processed, making possible decisions making by researchers. The Porifera also allows performing
an SLR
or SMS with mobility, knowledge sharing, flexibility, and integration between people and
technology.

IHC'13: XII Brazilian Symposyium on Human Factors in Computing Systems, October, 2013
DOI: 10.5555/2577101.2577142
This paper describes a study on the phenomenon of exploratory research on the Web. As a result,
we present a framework to support this type of information seeking with six dimensions: quality,
presentation, time, cognition and knowledge acquisition, personalization and collaboration. We
also present a tool that brings a new way to view the search history with features to organize
research projects. This tool aims to test some aspects of these dimensions, being based on a server and a
browser extension model. The experiments done showed results that demonstrate a good acceptability of
the features introduced.
